Foreign investors form Turkish companies through the same core registry system as local founders, yet their files have an extra operational risk: the identity, authority and document trail must match across every stage. The official Invest in Türkiye business-establishment guide states that the memorandum and articles are submitted online through MERSIS and that trade-registration transactions are carried out through that system. It also places the establishment stage at Trade Registry Directorates. MERSIS starts the electronic record. The Directorate processes the registration layer.
This is a 2026 working sequence for an investor or foreign corporate shareholder. It is general information, not legal or tax advice. The exact supporting-document set can change with the shareholder, signatory, company form and relevant Trade Registry Directorate, so obtain the current local checklist before filing.
What should be fixed before a foreign investor opens MERSIS?
Settle the legal form, shareholders, managers, registered address, activity description and capital plan before the first online entry. MERSIS records the company’s constitutional data. Reworking that data later can create mismatches between the articles, the registry file and authority documents.
The Ministry of Trade’s capital notice confirms the current statutory floors that apply to new entities: TRY 50,000 for a limited company and TRY 250,000 for a joint-stock company, effective from 1 January 2024. A non-public joint-stock company adopting the registered-capital system has a TRY 500,000 starting-capital floor. These figures are legal minimums, not a substitute for a realistic operating budget. Read the Ministry notice before selecting the form and capital entries.
Which documents deserve the closest foreign-investor review?
Start with identity and authority evidence. An individual shareholder’s passport details must be reproduced consistently. Where a foreign company is the shareholder, its current corporate record, decision-making authority and authorised signatory chain need to support the Turkish filing. If an attorney or representative will sign, the power of attorney must fit the contemplated acts.
Do not assume one generic international document pack works everywhere. Translation, notarisation, apostille or consular formalities depend on the issuing country and the particular document. Ask the receiving Trade Registry Directorate or a qualified adviser which version, translation and certification route applies before MERSIS data is final. A document that is valid in the investor’s home jurisdiction can still be unusable if its authority trail is incomplete for the Turkish registry file.
What is the correct MERSIS and Trade Registry sequence?
- Choose the company form, capital and governance model.
- Reconcile shareholder and authorised-signatory information against source documents.
- Prepare the company name, address and activity wording.
- Enter and submit the memorandum and articles online in MERSIS.
- Complete the Trade Registry Directorate stage with the ready supporting file and any required appointments or signatures.
- Retain the registered company data and follow the separate tax, banking and operational onboarding steps.
The Ministry’s Trade Registry page confirms that registry transactions are performed through MERSIS and the related records are kept there. Its legal role matters: MERSIS is the electronic system, while the Trade Registry is the public-registration framework. Treating them as one click is how a foreign-investor file becomes disorganised.
Can the company be registered in one day?
Invest in Türkiye says establishment at the one-stop-shop Trade Registry Directorate is completed within the same day. That statement concerns a file that is ready for the registry stage. It is not a promise that a cross-border shareholder structure, document certification, translation, bank arrangements and post-registration onboarding will all finish in a day.
For foreign investors, the dependable way to protect timing is to clear the document chain first. Check spelling, dates, passport numbers, company names and authority references across every source record. Then enter MERSIS once the structure has stopped moving. The official MERSIS portal describes the system as an electronic channel for trade-registry transactions, which supports that workflow.
What happens after the Trade Registry stage?
Registration is a milestone, not the end of the launch plan. Tax registration, bank or payment-provider onboarding, accounting setup, invoicing controls and any sector-specific licence analysis sit outside the simple MERSIS data-entry task. A foreign investor should allocate owners and dates for each workstream rather than treating the registry certificate as permission to start every activity immediately.

Foreign-investor MERSIS filing FAQ
Does MERSIS replace the Trade Registry Directorate?
No. MERSIS is the electronic registry-process layer. The Trade Registry Directorate remains the registration-processing stage.
Is there one fixed document list for every foreign shareholder?
No. The core identity and authority trail is common, but formalities depend on the investor, company form, issuing jurisdiction and registry requirements.
Can a foreign corporate shareholder use its home-country documents without review?
Do not rely on that assumption. Confirm current translation, certification and authority requirements before submission.
Does the legal capital minimum establish an adequate operating budget?
No. The statutory floor and the funding required for premises, payroll, tax and operations are different decisions.
Effective-date note: the cited Ministry capital notice states that the current minimum-capital changes took effect on 1 January 2024. All official sources were accessed on 20 July 2026.
